FAQ Section

How does the Hydraulic Gear Pump PVK-2B-505 maintain efficiency in compact excavators?

Answer: Its short-shaft design (JIS D2001 compliant) reduces bending stress by 40%, while vacuum-hardened 20MnCr5 gears (HRC 60-62) minimize wear. Each pump undergoes 100-cycle 0-220 Bar shock tests to validate compact durability.

How to diagnose low flow in the Hydraulic Gear Pump PVK-2B-505 system?

Answer: Step 1: Check suction filter (mesh ≤150μm). Step 2: Use our HGP-Tester to measure case drain flow (>5 L/min indicates worn gears). Step 3: Verify compensator valve setting with laser shim kits.

How does factory control reduce Hydraulic Gear Pump PVK-2B-505 lead times?

Answer: In-house sintered gear production (5-day cycle vs. 20-day outsourcing) + AI-driven inventory forecasting cut standard delivery to 72 hours for orders <100 units.

Can the Hydraulic Gear Pump PVK-2B-505 interface with telematics systems?

Answer: Yes. Optional IoT module (RS485/CAN J1939) transmits pressure, temperature, and efficiency data to HITACHI ConSite for predictive maintenance alerts.
